    TAF indicates that the following is a terminal aerodrome forecast. This line may also indicate an amended forecast (TAF AMD) or a corrected forecast (TAF COR) [3] KXYZ indicates the airport to which the forecast applies (ICAO airport code). 051730Z indicates that the report was issued on the 5th of the month at 1730 UTC (also known as Zulu ...

    Meteorological data includes wind speeds which may be expressed as statute miles per hour, knots, or meters per second. Here are the conversion factors for those various expressions of wind speed: 1 m/s = 2.237 statute mile/h = 1.944 knots 1 knot = 1.151 statute mile/h = 0.514 m/s 1 statute mile/h = 0.869 knots = 0.447 m/s

  6. Transcoding - Wikipedia

    en.wikipedia.org/wiki/Transcoding

    This re-encoding causes digital generation loss; thus if one wishes to edit a file repeatedly, one should only decode it once, and make all edits on that copy, rather than repeatedly re-encoding it. Similarly, if encoding to a lossy format is required, it should be deferred until the data is finalised, e.g. after mastering. Lower bitrate

    en.wikipedia.org/wiki/VOLMET

    VOLMET (French origin vol (flight) and météo (weather report)), or meteorological information for aircraft in flight, is a worldwide network of radio stations that broadcast TAF, SIGMET and METAR reports on shortwave frequencies, and in some countries on VHF too. Reports are sent in upper sideband mode, using automated voice transmissions.

  9. Data conversion - Wikipedia

    en.wikipedia.org/wiki/Data_conversion

    Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways. For example, computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks.
